Mobile Fidelity Sound Lab Original Master Record Sleeves (pack of 50)

These are the same high-quality inner sleeves Mo-Fi use for their vinyl releases. They are three-ply, anti-static, premium sleeves (similar to rice paper) and these are for 12" LP's. Back construction consists of a paper layer sandwiched between two sheets of high-density polyethylene (HDPE) with a translucent HDPE front.  They replace the original paper sleeve supplied with your album, to ensure your records remain clean and un-marked; and help prevent static build up.  

 In our opinion, they are the best sleeve available, having tried many others. (Touchstone2c comment)
